ok sweet thanks for the quick response im also gonna get some new springs when i get it and want too run the new 12mm bb associated springs, what should i run front and rear for indoor clay tracks ?

Understanding this is a bit subjective, what's the best servo and stock motor

My son has a upgraded b4.1 rtr, all the good stuff, how long is the +8 conversion upgrade take?

Don't be under the mistaken impression that more or less washers equals traction. It depends on what your car is doing. Having the rear roll center too high or too low will hurt traction when in the corners.

On corner exit, the test is very simple. If the car is loose and the situation gets worse when you apply more throttle, the roll center is likely too low and needs to be raised to reduce roll. If the car is loose and the situation gets better when you apply more throttle, then the roll center is likely too high and you need to lower it to increase roll.

Lower the roll center by adding washers. Raise the roll center by removing washers.

Before you do ANYTHING hunting for traction with your car, ensure your shock ends are screwed all the way in. 2wd cars without sway bars are extremely sensitive to shock down travel. Total chassis roll is limited by shock down travel much like a sway bar. Two limiters is the ticket on the b4.1, big bore or small bore, with the ends screwed all the way in obviously.

I like the lrp and reedy motor, run 13.5 and like the AE ds1015 servo and the airtronics 94770.

Your question is broad, but I have gone with savox 1257tg as I sort of swear by savox with quality and pricing as someone else may deny, but this servo is a quick one for 1/10th scales.

Shouldn't take too long, theres like 7 screws in the front along with all the rear bottom screws and the few near the shock tower... Just remount and all your electronics.

For servos I love the XP series, 1015 all the way (have used the 1313 in there and to be honest I could not see a difference in speed). Motor I like the Reedy and LRP but hear the Schurr (SP?) are really good as well.

I think the 1015 is great but for some reason I just like my Airtronics 94770's. The 1015 torque is way better speed is just a tick better on the 94770 though. Only had one Savox that my hobby shop sold me and was so tight in B4 moved it into SC and it works great and for under 40 bucks. Have not tried any high dollar Savox's though. My only rant that I have with them all is you don't get a nice single arm servo mount especially on the 1015 at $100.

If you ask 10 people this you will get 10 different answers. Pretty much depends on what you can afford. I personally run a radiopost blue speed servo and tekin 17.5.

Where did you get the information about the b4.2/b5? I'm curious as I have a b4.1 worlds coming in the mail as we speak so I'm just curious as to where the information saying the new buggy is coming out is?

Thanks

It's all speculation because someone heard Cavalaria was taking pictures of his buggy for a new box. I think it's one of those things if you truly believe in it will happen. Would be nice to see a new buggy though with all the new stuff on it.

I only offer general information. Car set ups and spring choice are beyond my pay grade. I think it's best to ask one of the other experts on here.

Search the thread, 4 or 5 possible new things, BBs, towers, hexs, steering rack, nothing for sure, like an iPhone.maybe the 4.2 will get google maps!

Ok cool thanks for that mate! Same thing around my track, don't know anyone running them. Just curious

Has anyone else tried them?

Thanks!

I'm hoping they put a gyro in it, that way no matter how you jump the buggy it will always land on it's wheels.
